Make a custom iPhone case showing any sound wave you like, frozen in time

Until now, most of the 3-D printed items I have seen have been slightly scratchy, brittle-feeling plastic prototypes sent to me by Kickstarter pitch-men.

But now Shapeways has teamed up with SoundCloud to bring us this cool-looking iPhone case which really shows the potential of 3-D printing. Using a custom app, you can freeze the sound-wave of your favorite piece of music and have it immortalized in a plastic case.
